The complexity of techniques such as Precise Point Positioning (PPP), or differential techniques that require the use of external sources of corrections, could be a disadvantage for users. On the other hand, a simple technique such as Single-Point Positioning (SPP) alone does not provide high-level accuracy. Nevertheless, the entry Galileo High-Accuracy Service (HAS), even if developed to be applied on PPP, could offer a positive impact on SPP. The objective of this study is the analysis of the effects of HAS on SPP, which are evaluated for Galileo and GPS, in single- and double-constellation mode. Results are encouraging, especially on the vertical channel, where some centimetric improvements are obtained.<\/jats:p>","DOI":"10.3390\/s23094223","type":"journal-article","created":{"date-parts":[[2023,4,24]],"date-time":"2023-04-24T03:04:08Z","timestamp":1682305448000},"page":"4223","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Application of \u201cGalileo High Accuracy Service\u201d on Single-Point Positioning"],"prefix":"10.3390","volume":"23","author":[{"given":"Antonio","family":"Angrisano","sequence":"first","affiliation":[{"name":"Department of Engineering, Messina University, 98166 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Silvia","family":"Ascione","sequence":"additional","affiliation":[{"name":"International PhD Programme \u201cEnvironmental Phenomena and Risks (EnPheR)\u201d, Department of Science and Technology, \u201cParthenope\u201d University of Naples, 80143 Napoli, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giovanni","family":"Cappello","sequence":"additional","affiliation":[{"name":"International PhD Programme UNESCO Chair \u201cEnvironment, Resources and Sustainable Development\u201d, Department of Science and Technology, \u201cParthenope\u201d University of Naples, 80143 Napoli, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6510-9240","authenticated-orcid":false,"given":"Ciro","family":"Gioia","sequence":"additional","affiliation":[{"name":"Independent Researcher, 21020 Brebbia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0860-2826","authenticated-orcid":false,"given":"Salvatore","family":"Gaglione","sequence":"additional","affiliation":[{"name":"International PhD Programme UNESCO Chair \u201cEnvironment, Resources and Sustainable Development\u201d, Department of Science and Technology, \u201cParthenope\u201d University of Naples, 80143 Napoli, Italy"},{"name":"Department of Science and Technology, \u201cParthenope\u201d University of Naples, 80143 Napoli, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,23]]},"reference":[{"key":"ref_1","unstructured":"Kaplan, E.D., and Hegarty, C.J.
